I'm trying a slow cooker lasagna recipe that popped up on Sparkpeople.com the other day.
Ooh. Let me know how it turns out.
I agree with Balmerhon, let us know how it turns our Bmore. 
Well, it was quite tasty. Here's the thing though, I'm not sure the benefits of making it in the slow cooker outweigh making it in the oven. In fact, the biggest pro would be you could make lasagna in the summer without heating up your house with the oven. The cons are you still have to cook the meat sauce before you put it together. And it only takes 3.5 hours to cook on low, so it's not something you can set to go in the morning before work, then have it ready when you get home.
So, in this instance I would think that regular lasagna is equally as good and faster to make.
